a request

Dear yeast netters,
I would like to clone an essential gene on the dependence of a Galactose
regulable promotor in order to create a conditional mutant of expression.
Is there anybody on the net who can provide me yeast vector(s) ready to use
for that purpose? I thank you in advance for your help and advices.
